ATTACHMENT T0 LINOTYIEE MACHINES.

Application filed September 13, 1921. Serial No. 500,313.

To all whom it may concern:

Be it known that I, ARTHUR CoELHo, a citizen of Brazil, residing at Brooklyn, New York, have invented certain new and useful Improvements in Attachments to Linotype Machines, of which the following is a specification.

This invention has for its object the providing, on a linotype machine, of means for using matrices with two fonts of type thereon, whereby the matrices may be used to present either font of type thereon effectively for the line of type to be formed therefrom. That is, the matrices have one font of type on one edge thereof and another font on the other edge. When the usual font or the font on the front edge is to be used, the matrices are used in the usual way but when the font on the other edge is to be used, the matrices are reversed to present the reverse edge for the molding operation. The means include automatic reversal of the matrices when the reverse edge is to be used and after use, the matrices are automatically rereversed before entering the distributor box so that they may be thus distributed in their normal position. These means include control means for determining which edge of the matrices will be present for the molding operation.

I have chosen the preferred embodiment of my invention for the purpose of illustrating it and making it clear but it is to be understood that this embodiment is used in an illustrative sense and not a limiting one for obviously the invention is capable of many different embodiments without (leparting from the spirit and scope thereof.

T have illustrated the chosen embodiment of my invention in the accompanying drawings in which Fig. 1 shows a side elevation of the magazine, the chutes leading from the magazine to the belt and the belt of a linotype machine. Fig. 2 is a perspective view of my gate means. Fig. 3 is a transverse longitudinal sesction of the second elevator plate of a linotype machine with my invention supplied thereto. Fig. 4 is a view similar to Fig. 3 except that the space band lever is moved inwardly to an engaging position. Fig. 5 is a view similar to Fi 4 except that the slide bar carried by the p ate is shown in full lines.

Fig. 9 is a view similar to Fig. 6 w th the latch depressed instead of open. Fig. 10 is a perspective view of the latch. Fig. 11 is a perspective view of the control rod. Fig. 12 is a detail of the manner of mounting of the control rod. Fig. 13 is a compound view showing the phases of action of the slide bar during its rotation. Fig. 14; is a perspective view of a usual second elevator. Fig. 15 is a perspective view of a usual guide pole. Fig. 16 is a perspective view of the manner in which the matrix slides off from the slide bar. Fig. 17 is the side elevation of one of my improved matrices. Fig. 18 is an enlarged view of detail. Fig. 19 shows diagrammatically howthe second elevator carries the second elevator plate.

The linotype machine will operate in the usual manner even though my invention is applied to that machine and the matrices will present their usual font of type or front edges for the molding operation so that my invention comprises the provision of means capable of reversing the matrices to present their second font of type for the molding operation, that is, means for reversing the matrices during their passage to the molding position, and then the re-reversing of the matrices before they are returned to the distributor box. To achieve this perfomance of reversing and re-reversing of the matrices, two attachments are required for the usual linotype machine which may be described as follows:

The reversing apparatus is composed of a system of reversing channels -21, attached to the front plate -22, of an ordinary linotype machine and at the top of the reversing channels is a gate -23, pivoted at the lower end of the magazine -24, of the linotype machine. The gate is provided with tongues -25, adapted to pass into and-bridge over the usual channels -26, of the linotype machine whereby when the gate is pivotally moved to bridge over the usual channels,-

posited in reverse position on the usual belt -27, of a linotype machine located at the bottom of the front plate -22, that is, when the gate -23, is open the matrices fall down the usual channels under the front plate and are deposited on the belt -27 in the usual position but when gate -23, is closed the matrices are conveyed past or over the mouth of the usual channels -26, into the reversing. channel s -21, after wh ch they are deposited onto the conveyor -27, in reverse position. From {the conveyor -27, they are carried into molding position in the usual The matrices are indicated by the nu-. meral -28 and are provided with a usual font on their front edge -29, and a supplemental font on their reverse edge 30. The dotted line and curved arrow on Fig. 1 indicate how they are reversed in falling down the reversing channels -21.

To attach to the usual machine these reversing channels -21, and their accessories, the upper glass part of the front plate -22, of the linotype machine is removed and in its place is substituted the gate -23, or other control means for determining which set of channels the matrix will fall down, and the reversing channels -21 are secured to the front plate -22 of the machine. The reversing gate means is preferably formed with tongues -25, in such a manner that the present or existing channels -26, on the machine will serve as the side walls. The lower end of the reversing channels will enter the lower end of the front plate for which that plate is out and arranged so that there will be no opening anywhere. 1

In order to re-reverse the matrices between the time they leave the molding posi tion and when they reach the distributor box, the following apparatus is provided: The usual second elevator -33 carries in the usual manner the second elevator plate -34, and the usual slide bar -35 is pivotally depended from the second elevator plate by means of a pin -36 on the slide bar so that the slide bar may rotate with the pin -36 as shown in Fig. 13 whereby after the matrices have been pushed onto the slide bar -35 the slide bar can be given a half turn during the upward travel of the second elevator. That is, the mat rices and slide bar -35, are re-reversed between the time they leave the molding position and the time they are ready to pass into the distributor box. That this action may be more clearly understood, reference is made to a gear -37 provided with internal pawls -38, co-acting with the pin -36, so that rotation of the gear -37, in one direction will rotate the pin -36 and its slide bar, but rotation of the gear -37 in the opposite direction will be without between, such as a resilient lining -46) is the control rod -47, having a hooked end -48 and a tooth -49, with the tooth -49 adapted to be engaged by the space band lever -50, when the latter slides into proximity therewith.

The usual space band lever -50, is a reciprocating element and as it moves toward the second elevator plate -34, (while transferring a line of matrices from the first to the second elevator), the inclined face -51 of the space band lever -50, engages a similiarly inclined portion -52 of the second elevator plate so that the space band lever -50, rides up on to-and along the second elevator plate as shown in Figs. 3, 4 and 5. Engagement of the inclined faces 51 and 52 (Fig. 3) causes the space band lever to ride up on to the elevator plate -34, (Fig. 5) in continued movement along the elevator plate -34 and causes the front edge of the space band lever -50 to engage the tooth -49, on the control rod -47, whereupon further movement of the space band lever along the elevator plate, pushes the rod -47 and the rack -39, longitudinally against the pressure of the spring -41 charging the spring so to speak, and during retraction of the rack -39, rotates the gear -37 but because of the pawls -38, the pin -36 and the slide remain unaffected thereby. As the space band lever recedes, the spring -41, is released pushing the rack -39, to its normal position and this movement to its normal position rotates the gear -37, so that the pawls -38, engage the pin 36 or rather the ratchet wheel -53 carried by the pin -36, and rotation of the pin -36, rotates the slide bar -34 with its matrices through 180 or one-half turn whereupon the matrices are in re-reversed position.

To avoid the matrices from falling off the slide bar as it is swung through its one-half turn, elbow shaped pins or latches -54, are provided near each end of the slide bar so that by means of the pressure from the spring -55 associated with each latch, the latch will have a tendency to project out over the to of the slide bar in a way to hold the ot er end of the pin or latch in a position to revent the matrices from falling down. he head of said latches projecting on the top of the slide :raeogree bar is pressed down over its other end to release the matrix. When the slide bar finishes its rotation or as the heads of the latches come under the plate. That is, when the heads of the latches are under the plate as shown in Fig. 9, the matrices are unlocked in position whereas during the turning of the slide bar and when the heads of the latches are free to be pressed upwardly by the spring -55, the matrices are in locked position on the slide bar.

To avoid having the slide bar turn before it is clear from transferring whereby it would cause the line of matrices to strike on the travel channels or on the second elevator guide pole on the provided pin means projecting from the edge of the second elevator plate for preventing rotation of the pin 36, the spring -61 associated with the pin -60 keeps the pin -36 in normally rotatable position but as the elevator plate passes down and contacts with the guide pole -62, the pin -60 is pressed inwardly to preventrotation of the pin -86 as the second elevaitpr falls.

The control rod -47 controls the rotation of the slide bar -35, and to that end it is rotatably mounted. If the matrices are being used with the usual font, the control rod -47, by means of its bent end or finger piece -48, is rotated through 90 degrees whereupon the tooth -49, of the rod is moved out of the path of the space band lever. In this position, the space band lever moves along the second elevator plate at the time of transferring the line of matrices from the first to the second elevator without engaging the rod -47 so that the rack bar -39 is not moved, and the slide bar is not rotated with respect 'to the second elevator plate which means that the matrices are not changed from their usual position during their return to the distributor box.

However, in the event the matrices have been used in their reverse position to mould the second font of type, the operator rotates the control rod -47 back to the position shown in Figs. 3, 4 and 5, where its tooth -49 will be engaged by the space band lever -50, and the rod slightly raised on its universal pivot -44. Continued movement inwardly of the space band lever charges the spring -11, which upon the receding of the space band lever, returns the rack bar -39, to initial position while during such return, the pin -36 and slide bar are rotated through 180 degrees and the matrices thereon are re-reversed readyfor the distributor box where they will return in initial or normal position.

. It will thus be seen that I have devised very simple attachments for the usual linotype machine, which, without materially disturbing any of its existing parts, will give it the usefulness of two such machines by adding to its capacity a second font of type.

What I claim is:

1. In combination in a linotype machine, a plurality of matrices having one font of type on one edge thereof and another font of type on the other edge, means having a plurality of sets of channels for rendering either font of type effective at the moulding position, a distributor box, and means for uniforml returning the matrices to the dis tributor ox in initial standard position.
